+## [0.27.0] - 2025-12-05 - Inline Dependency Graph
+
+### Added
+
+- **Dependency Graph in Initial Context (v0.27.0)**
+  - New `## Dependency Graph` section in initial context
+  - Shows file relationships without requiring tool calls
+  - Format: `services/user: → types/user, utils/validation ← controllers/user`
+  - `→` indicates files this file imports (dependencies)
+  - `←` indicates files that import this file (dependents)
+  - Hub files (>5 dependents) shown first
+  - Files sorted by total connections (descending)
+
+- **Configuration Option**
+  - `includeDepsGraph: boolean` in ContextConfigSchema (default: `true`)
+  - `includeDepsGraph` option in `BuildContextOptions`
+  - Users can disable to save tokens: `context.includeDepsGraph: false`
+
+- **New Helper Functions in prompts.ts**
+  - `formatDependencyGraph()` - formats entire dependency graph from metas
+  - `formatDepsEntry()` - formats single file's dependencies/dependents
+  - `shortenPath()` - shortens paths (removes `src/`, extensions, `/index`)
+
+### New Context Format
+
+```
+## Dependency Graph
+
+utils/validation: ← services/user, services/auth, controllers/api
+services/user: → types/user, utils/validation ← controllers/user, api/routes
+services/auth: → services/user, utils/jwt ← controllers/auth

+## Version 0.24.0 - Rich Initial Context 📋 ✅
+
+**Priority:** HIGH
+**Status:** Complete (v0.24.0 released)
+
+Enhance initial context for LLM: add function signatures, interface field types, and enum values. This allows LLM to answer questions about types and parameters without tool calls.
+
+### 0.24.1 - Function Signatures with Types ⭐ ✅
+
+**Problem:** Currently LLM only sees function names: `fn: getUser, createUser`
+**Solution:** Show full signatures: `async getUser(id: string): Promise<User>`
+
+```typescript
+// src/infrastructure/llm/prompts.ts changes
+
+// BEFORE:
+// - src/services/user.ts [fn: getUser, createUser]
+
+// AFTER:
+// ### src/services/user.ts
+// - async getUser(id: string): Promise<User>
+// - async createUser(data: UserDTO): Promise<User>
+// - validateEmail(email: string): boolean
+```
+
+**Changes:**
+- [x] Extend `FunctionInfo` in FileAST for parameter types and return type (already existed)
+- [x] Update `ASTParser.ts` to extract parameter types and return types (arrow functions fixed)
+- [x] Update `formatFileSummary()` in prompts.ts to output signatures
+- [x] Add `includeSignatures: boolean` option to config
+
+**Why:** LLM won't hallucinate parameters and return types.
+
+### 0.24.2 - Interface/Type Field Definitions ⭐ ✅
+
+**Problem:** LLM only sees `interface: User, UserDTO`
+**Solution:** Show fields: `User { id: string, name: string, email: string }`
+
+```typescript
+// BEFORE:
+// - src/types/user.ts [interface: User, UserDTO]
+
+// AFTER:
+// ### src/types/user.ts
+// - interface User { id: string, name: string, email: string, createdAt: Date }
+// - interface UserDTO { name: string, email: string }
+// - type UserId = string
+```
+
+**Changes:**
+- [x] Extend `InterfaceInfo` in FileAST for field types (already existed)
+- [x] Update `ASTParser.ts` to extract interface fields (already existed)
+- [x] Update `formatFileSummary()` to output fields
+- [x] Handle type aliases with their definitions
+
+**Why:** LLM knows data structure, won't invent fields.
+
+### 0.24.3 - Enum Value Definitions ⭐ ✅
+
+**Problem:** LLM only sees `type: Status`
+**Solution:** Show values: `Status { Active=1, Inactive=0, Pending=2 }`
+
+```typescript
+// BEFORE:
+// - src/types/enums.ts [type: Status, Role]
+
+// AFTER:
+// ### src/types/enums.ts
+// - enum Status { Active=1, Inactive=0, Pending=2 }
+// - enum Role { Admin="admin", User="user" }
+```
+
+**Changes:**
+- [x] Add `EnumInfo` to FileAST with members and values
+- [x] Update `ASTParser.ts` to extract enum members
+- [x] Update `formatFileSummary()` to output enum values
+
+**Why:** LLM knows valid enum values.
+
+### 0.24.4 - Decorator Extraction ⭐ ✅
+
+**Problem:** LLM doesn't see decorators (important for NestJS, Angular)
+**Solution:** Show decorators in context
+
+```typescript
+// AFTER:
+// ### src/controllers/user.controller.ts
+// - @Controller('users') class UserController
+// - @Get(':id') async getUser(id: string): Promise<User>
+// - @Post() @Body() async createUser(data: UserDTO): Promise<User>
+```
+
+**Changes:**
+- [x] Add `decorators: string[]` to FunctionInfo, MethodInfo, and ClassInfo
+- [x] Update `ASTParser.ts` to extract decorators via `extractNodeDecorators()` and `extractDecoratorsFromSiblings()`
+- [x] Update `prompts.ts` to display decorators via `formatDecoratorsPrefix()`
+
+**Why:** LLM understands routing, DI, guards in NestJS/Angular.
+
+**Tests:**
+- [x] Unit tests for ASTParser decorator extraction (14 tests)
+- [x] Unit tests for prompts decorator formatting (6 tests)

+```typescript
+// Add to initial context:
+
+// ## Dependency Graph
+// src/services/user.ts: → types/user, utils/validation ← controllers/user, api/routes
+// src/services/auth.ts: → services/user, utils/jwt ← controllers/auth
+// src/utils/validation.ts: ← services/user, services/auth, controllers/*
+```
+
+**Changes:**
+- [x] Add `formatDependencyGraph()` to prompts.ts
+- [x] Use data from `FileMeta.dependencies` and `FileMeta.dependents`
+- [x] Group by hub files (many connections)
+- [x] Add `includeDepsGraph: boolean` option to config
+
+**Tests:**
+- [x] Unit tests for formatDependencyGraph() (16 tests)
+- [x] Unit tests for includeDepsGraph config option (5 tests)
+
+**Why:** LLM sees architecture without tool call.
+
+---
+
+## Version 0.28.0 - Circular Dependencies in Context 🔄
+
+**Priority:** MEDIUM
+**Status:** Planned
+
+### Description
+
+**Problem:** Circular deps are computed but not shown in context
+**Solution:** Show cycles immediately
+
+```typescript
+// Add to initial context:
+
+// ## ⚠️ Circular Dependencies
+// - services/user → services/auth → services/user
+// - utils/a → utils/b → utils/c → utils/a
+```
+
+**Changes:**
+- [ ] Add `formatCircularDeps()` to prompts.ts
+- [ ] Get circular deps from IndexBuilder
+- [ ] Store in Redis as separate key or in meta
+
+**Why:** LLM immediately sees architecture problems.
+
+---
+
+## Version 0.29.0 - Impact Score 📈
+
+**Priority:** MEDIUM
+**Status:** Planned
+
+### Description
+
+**Problem:** LLM doesn't know which files are critical
+**Solution:** Show impact score (% of codebase that depends on file)
+
+```typescript
+// Add to initial context:
+
+// ## High Impact Files
+// | File | Impact | Dependents |
+// |------|--------|------------|
+// | src/utils/validation.ts | 67% | 12 files |
+// | src/types/user.ts | 45% | 8 files |
+// | src/services/user.ts | 34% | 6 files |
+```
+
+**Changes:**
+- [ ] Add `impactScore: number` to FileMeta (0-100)
+- [ ] Compute in MetaAnalyzer: (transitiveDepByCount / totalFiles) * 100
+- [ ] Add `formatHighImpactFiles()` to prompts.ts
+- [ ] Show top-10 high impact files
+
+**Why:** LLM understands which files are critical for changes.
+
+---
+
+## Version 0.30.0 - Transitive Dependencies Count 🔢
+
+**Priority:** MEDIUM
+**Status:** Planned
+
+### Description
+
+**Problem:** Currently only counting direct dependencies
+**Solution:** Add transitive dependencies to meta
+
+```typescript
+// FileMeta additions:
+interface FileMeta {
+    // existing...
+    transitiveDepCount: number;    // how many files depend on this (transitively)
+    transitiveDepByCount: number;  // how many files this depends on (transitively)
+}
+```
+
+**Changes:**
+- [ ] Add `computeTransitiveDeps()` to MetaAnalyzer
+- [ ] Use DFS with memoization for efficiency
+- [ ] Store in FileMeta
+
+**Tests:**
+- [ ] Unit tests for transitive dependencies computation
+- [ ] Performance tests for large codebases
